If you do, can you ask someone to take a picture of it so we can use it for the summer session?
(Seriously--take a good break--eat chocolate--good for a walk--stare at clouds--balance the checkbook--cook a meal--take a nap. If you take your mind off it for a short while, you will find that your mind has been sorting things in the background, and solutions seem more obvious. Of course, you'll have less time left to
write them, but they'll come quicker. Don't take too long a break.
When I got most stuck, I went to a party at a champagne bar and ate canapes for a few hours and then wandered through Chinatown in the dark of the night. My muse likes that sort of thing. She likes chocolate and eggplant parmesan, too. Courting your muse is not the same thing as procrastinating--you have to bring her along with you wherever you go, and know that she's watching everything you do.
A wise man at the champagne bar said "When you get stuck, go deeper into your characters. Everybody has the reason they
think is the reason for what they do, and a
real reason for doing it, too. When you know all three reasons, you'll know what comes next."
